Elastic fabric

ELASTIC FABRIC No Drawing.

This invention relates to elastic fabric and relates more particularly to the preparation of an elastic fabric that is not as readily soiled as the prior material and which can be cleaned readily.

An object of my invention is to prepare elastic fabric that does not readily soil and which is easily cleansed. Another object of my invention is to prepare elastic fabric containing rubber or other resilient thread and yarns of cellulose acetate or other organic de rivatives of cellulose;

Elastic fabrics are used widely for making articles such as garters, corsets and the like. Such elastic fabrics contain rubber threads for imparting resiliency and also yarns of fibres such as cotton, natural silk or reconstituted cellulose. Such articles are-generally worn close to the human body and therefore :0 end to soil readily. Cotton, natural silk,. 'wool or reconstituted cellulose fibres that have heretofore been employed are quite pervious to dirt, grease, moisture, perspiration and the like and therefore become soiled very 3| readily. Moreover this soiling is so deepseated that in order to clean the elastic fabric,

su'ch drastic scouring must be resorted to that the rubber is deteriorated to such an extent that the utility of the fabric is impaired or 80 even destroyed.

I have found that if elastic fabric is made by employing yarns containing filaments of cellulose acetate or other organic derivatives of cellulose instead of the yarns of the other textile fibres heretofore employed, the resulting fabric is superior to those heretofore made. The cellulose acetate yarn is relatively impervious to dirt, grease, moisture, perspiration and the like and'therefore the elastic fabric containing it does not soil readily. Moreover when such fabric does soil, a very light washing in water of relatively low temperature containing a mild soap is sufficient to clean the same, and such a light washing does not appreciably impair Application filed August 8, 1930.

the properties of the rubber threads. A further advantage accruing from the use of the cellulose acetate yarn in accordance with this invention is that perspiration does not tend to weaken the same as in the case of w other textile fibres.

In accordance with my invention the elastic fabric may be made by weavin or knitting yarns containing filaments o cellulose acetate or other organic derivatives of celu lulose with threads of rubber or other elastic or resilient material in any known or suitable manner. While this invention is described specifically in connection with yarns containing cellulose acetate, yarns containing other organic derivatives of cellulose such as organic esters of cellulose and cellulose ethers may be employed. Examples of organic esters of cellulose other than cel lulose acetate are cellulose formate, cellulose 5 propionate and cellulose butyrate, while examples of cellulose ethers are ethyl cellu lose, methyl cellulose and benzyl cellulose.

Elastic fabric made in accordance with this invention may be used for making'wear- 7o ing apparel consisting in whole or in part of such elastic fabric. By way of example, garters (both hose and sleeve), belts, corsets, girdles, brassieres, trouser braces, elastic bands for bloomers, trousers and the like may be made with my elastic fabric. Another use for elastic fabric is in the making of athletic or surgical bandages or articles such as ankle braces, stockings, sleeves, abdominalbraces and the like.

his to be understood that the foregoing descriptionlis given merely by way of illustration, and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

1. An elastic fabric containing yarns of an organic derivative of cellulose and rubber threads.

2. An elastic fabric containing yarns of cellulose acetate and rubber threads.

3. Wearing apparel com rising an elastic fabric contalning yarns of organic derivatives of cellulose and rubber threads.

4. Wearing apparel comprising an elastic fabric containing yarns of cellulose acetate and rubber threads.

In testimony whereof, I have hereunto subscribed my name.
